3D‐Printable, Biodegradable, and Conductive/Piezoionic Hydrogel ‘E‐Skin’ With Robust Antibacterial Properties for Wound Healing and Wireless Human‐Machine Interface Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional MXene‐integrated GelMA/alginate hydrogel reinforced with TEMPO‐modified nanocellulose is engineered via dynamic covalent, ionic, and hydrogen bonding. The resulting piezoelectric, adhesive, antimicrobial, and 3D‐printable patch enables motion sensing and accelerates wound healing by promoting keratinocyte migration and collagen ...

Ul'anov type inequalities for moduli of smoothness [PDF]

open access: yes, 2012
Let T denote the interval [-?, ?]. In this work we investigate the inequality of Ul'yanov type for moduli of smoothness of an integer order in the Lp (T), p ? 1 spaces.

Geometric characterization of generalized Hajłasz-Sobolev embedding domains

open access: yesAdvances in Nonlinear Analysis
In this article, the authors study the embedding properties of Hajłasz-Sobolev spaces with generalized smoothness on Euclidean domains, whose regularity is described via a smoothness weight function ϕ:[0,∞)→[0,∞)\phi :\left[0,\infty )\to \left[0,\infty ).

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Global Smoothness Preservation and Simultaneous Approximation by Generalized Discrete Singular Operators [PDF]

open access: yes, 2017
In this chapter we continue with the study of generalized discrete singular operators over the real line regarding their simultaneous global smoothness preservation property with respect to Lp-norm for 1 ≤ p ≤ ∞, by involving higher order moduli of ...

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

open access: yesAdvanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...
